REGENERATIVE BURNER.

SPECIFICATION forming part of Letters Patent No. 579,687, dated March 30, 1897. Application filed April 13, 1893. $erial No. '70,201. (No model.)

To all whom it may con/887%:

Be it known that we, WILLIAM R. SWIFT and THoMAs GoRDoN, of the city, county, and State of New York, have invented a new and useful Improvement in Regenerative Burners, of which the following is a specification.

We will describe a regenerative burner embodying our improvement, and then point out the novel features lin a claim.

ro In the accompanying drawings, Figure 1 is a central Vertical section of a regenerative lamp and burner, the latter of which embodies our improvement. Fig. 2 is a central vertical section of a diaphragm of modified form.

Fig. 3 is a' central Vertical section of a regenerative lamp somewhat modified in construction.

Similar letters of reference design ate corresponding parts in all the figures.

zo Referring first to Fig. 1, A designates a gasconduit, here shown as made in the form of apipe, provided at its lower end with a screwcoupling a, capable of engagement with the nipple of a gas-fixture.

At the top of the gas-conduit A is a central gas-Chamber a', here shown as made in the form of a cap or hollow plug, whence eXtend radially a number of tubes (L2, which serve to supply the gas to a gas-chamber B.

The gas-chamber B is of annular form, it being in the present instance made of two sheet-metal shells b' 292. The inner shell b' is engaged with the tubes (L2. A convenient way of engaging the tubes a? with the cap or 3 5 plug a' is to provide the parts with screwthreads on theiradjacentsu'rfaces. The ends of the tubes which support the shell b' may be united with said shell by brazing. The lower edge of the shell b' is turned inwardly 40 in the form. of a fiange 123. That portion of the shell b' forming the upper portion of the gas-Chamber B is turned outwardly to form a shoulder 194. Above this shoulder the shell 112 engages with the shell b', the means of engagement here represented being screwthreads. At the lower extremity the shell 192 is bent inwardly to lap under the flange 173 of the shell b'. The lower portion of the shell 172 is provided with perforations b, whence the gas issues in jets and is burned.

O designates a shell through which passes air necessary for combustion. It may be made of sheet metal, and, as here shown, it has a lower cylindric portion c', a contracted conical portion 02, and a smaller cylindrical portion C3. The upper extremity of the latter is turned inwardly to formaflange 04, and this may bear against the inwardly-turned lower edge of the shell bg, comprised in the gas-Chamber.

We have shown the lower cylindric portion c' of the shell O as provided with an integral outwardly-extending flange 05, formiug a gallery or support for a combustion-chamber, which in the present example of ourimprovement is made in the form of a glass globe D, provided with a cylindrical base portion cl, that loosely surrounds the lower cylindric portion c' of the shell O, and surmounted by a cylindric portion d'. Spring-fingers 0G, exro tending upwardly from the gallery-fiange 05, impinge against the outer side of the cylindrio base portion cl of the combustion-chamber D, thereby holding the same in place.

A convenient means of supporting the shell C, and consequently the combustion-chamber, consists in arms a, extending outwardly from the coupling a to a ring (LG, upon which the flange or gallery 05 rests.

Preferably we employ in the lower part of the shell C a perforated or reticulated diaphragm E, so as to prevent air ascending in gusts. Part of the air escapes from the perforat-ions in the shell O, so as to supply air to the lower mantle or surface of the fiame. Another portion of the air fiows upwardly past the tubes a, to support the combustion on the upper mantle or surface of the flame. This portion of the air passes through the air-Chamber G,' and thence to a defiector H, whereby air is directed against the fiame.

The chamber G, as here shown, is formed partly by the cylindric upper portion of the shell b', formiug part of the gas-Chamber B, and partly by a cap g, surmounting said shell. The upper portion of the shell b' is shown as Vertically slotted, and hence as being pro- Vided with a number of upright arms between the slots g'. The capgmay be made of sheet metal and integral with the deflector I-I.

When the chamber G is constructed in the manner described, it will be advantageous IOO to introduce a diaphragm I, having numerous small perforations below the slots or openings (/C As here shown, the dia-phrag'm I is provided with a dowmvardly-extending rim, fitting inside of the shell b' and resting upon an outwardly-turned portion of the latter.

Te may use a reflector J, consisting,r of an annular shell around the defiector II and resting` upon an outwardly-turned lange or bead on the lower extremity of the latter.

In Fig. 2 we have shown that the diaphragm I instead of having a number of perforatons may be provided with a single central opening. Each form has advantag'cs for a particular kind of gas.

In Fig. the construction is substantially the same as that described in connection with Fig. 1, exceptinp; as to some features which we will nowdescribe. The central gas-chamber (U at the upper extremity of the gas-conduit A' has a cap (L7. This may be made with a downwardly-extending rim capable of screwing into the upper portion of the body.

Instead of having; large openings for the escape of air from the air-heatingr chamber G, the form of our iuvention illustrated by Fig'. 3 has a number of perforations, it thus being enabled to regulate of itself the escape of the air, instead of requiring the diaphragm I for that purpose.

That we claim as our invention, and desire to secure by Letters Patent, is-

In a regenerative burncr, the combination of a nipple for connectng with a gas-fixture, a gas-supply pipe extendinr upwardlytherefrom, an annular upwardly-extended gasburner chamber, concentric with the gassupply pipe and proyided with a circular row of gas-outlcts opening downwardly at its base, an air-delector extending downwardly and surroun din g the gas-burncr ehamber and separated a distance therefrom for the passage of air, a diaphragm separatng the space between the outer surface of the gas-burncr Chamber and the deflector from the space through the annular gas-burncrchamber, a globe-support below the burncr and concentric with and sustained by the gas'supply pipe, a globe supported by the globe'suppoit, and a shell surrounding the gas-supply pipe and extending from the globe-support to the base portion of the annularburner-chamber, inward of its row of gas-outlets so as to form with the inner wall of the gas-bl'rner chamher part of a conduit to the annular space between the dellector and the burncr-chamher, said shell having' perferations for supplying air to the base of the burncr, substantially as speeilied.

In testimony whereof we have signed our names to this speeificationin the prescnce of two subscribing witnesses.
